Mean aerodynamic chord.

Mean Aerodynamic Chord (MAC) The width of the wing, or straight-line distance from the leading edge to the trailing edge, on an airplane is known as the chord. If the leading edge and the trailing edge of a wing are parallel, the chord is equal at all points along the entire length of the wing. The average length of the chord, or MAC, of a tapered wing is more …

The mean aerodynamic chord is used for calculating pitching moments. [4] Standard mean chord. Standard mean chord (SMC) is defined as wing area divided by wing span: [5] =, where S is the wing area and b is the span of the wing. Thus, the SMC is the chord of a rectangular wing with the same area and span as those of the given wing.

Aerodynamic Center AC by a safety factor called Static Margin, which is a percentage of the MAC (Mean Aerodynamic Chord). Static Margin should be between 1% and 10% for a good stability. Low Static Margin gives less static stability but greater elevator authority, whereas a higher Static Margin results in greater static

decreases toward the tip. In relation to the aerodynamics of the wing, the average length of the chord on these tapered swept-back wings is known as the mean aerodynamic chord (MAC). On these larger airplanes, the CG is identified as being at a location that is a specific percent of the mean aerodynamic chord (% MAC).

Mean Aerodynamic Chord (MAC) is the average (mean) chord length across a wing. Think of it like taking lots of slices of a wing, measuring their length, and then finding the average of those lengths. The point along the wing … 2.2. Mean Aerodynamic Chord . The mean aerodynamic chord (MAC) is usually used to express the travel of the aircraft’s center of gravity (CG) in terms of % MAC. The longitudinal position of the MAC is necessary to determine the lever arm between the tail surfaces and the wing configuration for sizing the tail The Mean Aerodynamic Chord (MAC) does more than guide design and aid in flight operations; it significantly impacts an aircraft’s performance.
